Constructor Detail

PeerSocketAddress

public PeerSocketAddress(InetAddress inetAddress,
                 int tcpPort,
                 int udpPort)

Creates a PeerSocketAddress including both UDP and TCP ports.

Parameters:

inetAddress - The InetAddress of the peer. Can be IPv4 or IPv6

tcpPort - The TCP port

udpPort - The UDP port

PeerSocketAddress

public PeerSocketAddress(InetAddress inetAddress,
                 int tcpPort,
                 int udpPort,
                 int offset)

Creates a PeerSocketAddress including both UDP and TCP ports. This constructor is used mostly internally as the offset is stored as well.

Parameters:

inetAddress - The InetAddress of the peer. Can be IPv4 or IPv6

tcpPort - The TCP port

udpPort - The UDP port

offset - The offset that we processed

Method Detail

create

public static PeerSocketAddress create(byte[] me,
                       boolean isIPv4,
                       int offsetOriginal)

Converts a byte array into a PeerSocketAddress.

Parameters:

me - The byte array

isIPv4 - Whether its IPv4 or IPv6

offsetOriginal - The offset from where to start reading in the array

Returns:

the PeerSocketAddress and the new offset

create

public static PeerSocketAddress create(io.netty.buffer.ByteBuf buf,
                       boolean isIPv4)

Decodes a PeerSocketAddress from a Netty buffer.

Parameters:

buf - The Netty buffer

isIPv4 - Whether the address is IPv4 or IPv6

Returns:

the PeerSocketAddress and the new offset

createSocketTCP

public static InetSocketAddress createSocketTCP(PeerSocketAddress peerSocketAddress)

Creates the socket address to reach this peer with TCP.

Parameters:

peerSocketAddress - The peer's PeerSocketAddress

Returns:

The socket address to reach this peer with TCP.

createSocketUDP

public static InetSocketAddress createSocketUDP(PeerSocketAddress peerSocketAddress)

Creates the socket address to reach this peer with UDP.

Parameters:

peerSocketAddress - The peer's PeerSocketAddress

Returns:

The socket address to reach this peer with UDP.

inetAddress

public InetAddress inetAddress()

Returns:

The inernet address, which is IPv4 or IPv6.

tcpPort

public int tcpPort()

Returns:

The TCP port.

udpPort

public int udpPort()

Returns:

The UDP port.

offset

public int offset()

Returns:

The offset.

toByteArray

public byte[] toByteArray()

Serializes the PeerSocketAddress to a byte array. First, the ports (TCP, UDP) are serialized, then the address.

Returns:

The serialized PeerSocketAddress

toByteArray

public int toByteArray(byte[] me,
              int offset)

Serializes the PeerSocketAddress to a byte array. First, the ports (TCP, UDP) are serialized, then the address.

Parameters:

me - The byte array to serialize to

offset - The offset from where to start

Returns:

How many data has been written

size

public int size()

Calculates the size of this PeerSocketAddress in bytes. Format: 2 bytes TCP port, 2 bytes UDP port, 4/16 bytes IPv4/IPv6 address.

Returns:

The size of this PeerSocketAddress in bytes.

size

public static int size(boolean isIPv4)

Calculates the size of a PeerSocketAddress in bytes. Format: 2 bytes TCP port, 2 bytes UDP port, 4/16 bytes IPv4/IPv6 address.

Parameters:

isIPv4 - Whether the address is IPv4 or IPv6.

Returns:

The size of this PeerSocketAddress in bytes.
